Question

(04.03 LC)

Which of the following is a single replacement reaction?
Ba(OH)2 + H₂SO4 → BaSO4 + 2H₂O
O2Mg + O₂2MgO
O H₂O+ CO2 → H₂CO3
O Zn + H₂SO4 → ZnSO4 + H₂

Answer 1

D.) Zn + H₂SO₄ ----> ZnSO₄ + H₂

Step-by-step explanation:

Single-Replacement Reaction: a reaction in which an element in a compound is swapped with another element

ex.) Zn + H₂SO₄ ----> ZnSO₄ + H₂

Double-Replacement Reaction: a reaction in which a cation in one compound is swapped with a cation in another

ex.) Ba(OH)₂ + H₂SO₄ ----> BaSO₄ + 2 H₂O

Synthesis Reaction: a reaction in which two or more elements/compounds combine to form a new molecule

ex.) 2 Mg + O₂ ----> 2 MgO

ex.) H₂O + CO₂ ----> H₂CO₃
